Hey Mei Hong , how are you getting to Xi ’ an next week ?   I ’ m not sure yet . I may take the train but then again I might take the bus .   Yeah but the bus takes a long time . You could fly - it ’ s not so expensive these days .   Really ? Maybe I ’ ll do that then .   Ok well , you let me know your schedule and I ’ ll book a ticket for you .   Ok . Thanks for that !
